Husband masturbating

So I’m pregnant and I wasn’t horny for the first trimester at all I was just too tired and honestly just too busy throwing up. But the past month - month and a half my sex drive has been through the roof (we’ve been having sex atleast once a day but closer to 2-3 times..) when I woke up this morning I asked my husband if he was hungry and he just said kinda but he’s super tired so I decided to surprise him with breakfast in bed then have some morning sex. When I got to the bedroom he was awake and there was a roll of toilet paper on the bed, I was like whys this here and was like did you just masturbate ? And he stared to giggle and said yes. I immediately got upset and just walked away... I think because of hormones with the pregnancy didn’t help. He came out to eat breakfast with me and we were talking and he was like yeah I masturbated last night too while you were sleeping... ( we had sex in the late afternoon) and like beside me!! Am I over reacting and it’s just the pregnancy? I feel so hurt and feel like he’s addicted to sex and masturbating. I talked to him saying it upset me and he just responded with well I didn’t think you were in the mood.
